| <p>This is a regression test for https://bugs.webkit.org/show_bug.cgi?id=50434. It verifies that a marquee does not animate when scrollAmount is set to 0 by script.</p> |
| <script> |
| if (window.testRunner) |
| testRunner.waitUntilDone(); |
| |
| onload = function() |
| { |
| var marquee = document.createElement("marquee"); |
| marquee.innerHTML = "Test"; |
| marquee.width = "100px"; |
| // We need a non-zero scroll delay and amount for marquee timer to start. |
| marquee.scrollAmount = 6; |
| marquee.scrollDelay = 100000; |
| document.body.appendChild(marquee); |
| // Force layout now, so that marquee starts its timer. |
| marquee.offsetTop; |
| // Verify that changing scrollAmount to 0 actually stops the marquee (the bug |
| // was that starting with 0 worked correctly, but changing to 0 did not). |
| marquee.scrollAmount = 0; |
| // Set the delay to a very low value, so that scrolling would have occured before notifyDone() if not stopped. |
| marquee.trueSpeed = true; |
| marquee.scrollDelay = 1; |
| if (window.testRunner) { |
| setTimeout(function() { |
| testRunner.notifyDone(); |
| }, 10); |
